Exact-fit DDR5 RDIMM kit

This 64 GB kit consists of two 32 GB DDR5-6400 Registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDW-40C-SP9F memory controller expects. The 288-pin modules install directly into the board's DDR5 slots for immediate recognition at full rated speed.

Capacity and headroom

The dual-rank 2Rx4 organisation delivers 64 GB total capacity, allowing the server to run fully populated at DDR5-6400 without down-clocking. ECC corrects single-bit errors on the fly while the registered buffer offloads the controller, so stability is maintained across every populated channel under sustained workloads.

Registered ECC requirement

Only DDR5 Registered ECC RDIMMs with 1.1 V operation and CL52 timing match this motherboard's specification; UDIMMs, SODIMMs or non-ECC modules will not function. Verify your system manual for approved population order before installation.

Questions about this item

Will this 64GB DDR5-6400 ECC RDIMM kit run alongside existing DDR5 modules in my Supermicro X14SDW-40C-SP9F?

Mixing DIMMs of different ranks, speeds, or capacities can prevent the server from training memory at DDR5-6400 CL52 1.1V. The board manual lists the approved population order and maximum capacity per channel; follow that guide before adding these 2Rx4 Registered modules to any occupied slots.

How can I verify the kit is recognised at DDR5-6400 CL52 with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory frequency reads 6400 MT/s, CAS latency shows CL52, voltage is 1.10 V, and ECC status is enabled. The operating system should report 64 GB total with ECC correctable-error counters incrementing cleanly under load.

What is included in the box and do I need any extra parts to install it?

The package contains two 32 GB 288-pin DDR5 RDIMMs, giving 64 GB total. No heat spreaders, cables, or tools are supplied; the modules insert directly into the motherboard's DDR5 RDIMM slots.
